2025 Fantasy Outlook

$Signed a one-year, minor-league contract with the White Sox in January of 2025.
Sent to minor-league camp
PChicago White Sox  AAA
March 17, 2025
The White Sox reassigned Heasley to minor-league camp Monday.
ANALYSIS
Heasley, 28, attended camp as a non-roster invitee after he had previously turned in a 5.89 ERA and 89:55 K:BB in 139 career innings in the big leagues over parts of the last four seasons. Though he was sharp over his four Cactus League appearances in allowing just two hits and two walks while striking out three over four scoreless frames, Heasley will need to distinguish himself over a larger sample at Triple-A Charlotte before he gets a look with the White Sox.

2023 Fantasy Outlook
Heasley spent a majority of 2022 in the majors, but the fact that he averaged less than five innings per start (104 innings across 21 starts) shows just how poorly it went. He had a 5.28 ERA, 1.49 WHIP and 70:47 K:BB in the majors while adding a 4.35 ERA, 1.15 WHIP and 45:10 K:BB across 39.1 innings at Triple-A Omaha. Entering his age-26 season, the minor-league numbers suggest at least some modest improvements could be on the way if he can cut down on his 4.1 BB/9 and 1.6 HR/9 at the major-league level. The right-hander has solid movement on his fastball and curveball, but he struggled to avoid hard contact, giving up a 45.3 percent hard-hit rate last year. At best, Heasley's a back-of-the-rotation starter, though he could also be in contention to work as a swingman if the Royals go with five starters to begin 2023. Another tour in Triple-A also remains a possibility.
